I'll try to answer your questions the best I can.
My question is this do bucks use the same bedding area all year or is it possible that based on this years winter the buck is bedding closer to the food?
The answer to this is yes and no. If its in a spot that is nearly impossible to get to without being seen or smelled, the bed may be a primary bed. Now, bucks have multiple primary beds, which get used throughout the year. The difference between them usually is the wind advantage and food sources. Food sources that are typically available year after year will yield primary beds near them. Then, the difference between them is the wind advantage. Some of their beds work for the deer to smell whats coming from the west, or some from the east..you get what Im saying. There is USUALLY a wind advantage to the beds, and they will use that bed during those winds.
There are also alot of temporary beds this time of year, especially when there is this much snow on the ground and food is limited. Deer will bed near the food source for just a couple days, and then move onto a better food source in the spring/summer/fall, and bed in one of his primary beds near there.
I have a great stand site very close by but if the buck is bedded there it is impossible to get there without being seen or smelt.
You can be sure thats exactly why the bed is there. They dont just bed anywhere..not so much to do with your stand being there, but their beds are VERY strategically placed..they can usually see one direction and smell the other direction. They may also be somewhere that doesnt allow anything to sneak up on them from behind, etc. In hilly terrain, they are masters at using rising air thermals to bring scent from valleys up to them, while keeping the prevailing wind to their back, and smelling anything from behind them.
If he is bedded in that bed, and you walk out to your stand nearby, if you get seen or smelt, he may not bolt, I can guarantee you that he wont leave his bed til after dark. Once the summer rolls around, dont go near the bed (unless you can set up somehow to kill him very near it) or he will not be using that bed for long. Their bed is their sanctuary, they feel safe there. Human intrusion is not tolerated there, because they no longer feel safe once they know they have been found. Once they dont feel safe there anymore, they will move to a different bed..
